. 3 Claims.

The invention relates to improved track sanding means, and the primaryobject of the invention is to provide an arrangement of this characterwherein the sand dispensing hoses are caused to follow the deflection ofthe Wheels of the locomotive or the like, relative to the tracks, as innegotiating a turn, whereby the waste and misapplication of the sand toone or the other side of the tracks which commonly takes place inpresent arrangements of this character is eliminated, and the sand isefficiently and continuously applied to the tracks in front of thewheels.

Other objects and advantages of the invention will be apparent from areading of the. following description taken in connection with theappended drawings, wherein a preferred embodiment of the invention isshown.

In the drawings:

Figure 1 is a fragmentary side right hand side elevational View of arailway locomotive equipped in accordance with the present invention.

Figure 2 is a fragmentary transverse vertical sectional View takenthrough Figure 1 along the line 22 and looking in the direction of thearrows with portions of the locomotive shown in phantom lines.

Figure 3 is a fragmentary enlarged and contracted front elevational viewof the track sanding arrangement.

Figure 4 is a horizontal sectional view taken through Figure 3 along theline 6-5 and looking downwardly in the direction of the arrows.

Figure 5 is an enlarged fragmentary transverse vertical sectional viewtaken along the line 5-5 of Figure 3 and looking toward the left in thedirection of the arrows.

Figure 6 is a fragmentary transverse vertical sectional View takenthrough Figure 3 along the line 6-6 and looking toward the left in thedirection of the arrows.

Referring in detail to the drawings, numerals 5 and 6 generallydesignate similar vertically elongated brackets which are welded orotherwise suitably secured to depend from the forepart of the frame orchassis of the locomotive 1 between 4 the front portions of the frontdrive wheels 8 as indicated in Figure 1 of the drawings, the brackets 5and 6 being transversely spaced between the drive wheels 8 and equippedon their lower ends with L-shaped terminals 9 with cotter keys or thelike H] passed through openings H and I2, respectively, formed in theupper end of the standard portion of the terminal 9 and a point ofcorresponding elevation on the body of the bracket as indicated inFigure 5 of the drawings, the purpose of the terminals 9 and the cotterkeys 10 being to retain for horizontal lateral sliding support the slidebar which is generally designated l3 which is of generally rectangularcross-section, with a length adjusting 'fturnbuckle l connected in theslide bar between the brackets 5 and 6 as indicated in Figures '3 and4.

Laterally outwardly beyond the brackets 5 and 6 the slide bar l3 hasthreaded terminals IS on which are longitudinally adjustably threadedthe clevises I6 between whose arms are carried the rollers I? which bearagainst the inner sides of the marginal portions of the front drivewheels 8.

The portions of the slide bar [3 between the adjacent brackets and theroller equipped clevises have welded or otherwise secured thereto theforwardly and downwardly and laterally outwardly bent arms l8 whoselaterally outward terminals are pivoted as indicated by the numerals l9between the pairs of ears 20 on the downwardly and rearwardly curvedauxiliary sand discharging pipes 2| which reach down to the tracks 22 asindicated in Figures 1 and 2 to discharge the sand on the rail head infront of the forward driving Wheels 8.

The auxiliary sand discharging pipes 21 are connected in communicationwith the regular equipment sand distributing pipes 2| which depend fromthe locomotive chassis in front of the front drive wheels, by a flexiblecoupling 24 which permits the auxiliary pipes 6 and 2i to be pivoted andlaterally deflected by the connection of the arms l8 thereto, inresponse to the shifting motion of the slide bar l3, produced by thedeflection of the wheels 8 in contact with the rollers I! on theopposite ends of the slide bar. As the wheels 8 are deflected relativeto the locomotive chassis the slide bar [3 is adjusted to keep the lowerend of the auxiliary sand discharging pipes 2| positioned to deposit thesand on the rail head.

Although there is shown and described herein a preferred embodiment ofthe invention it is to be understood that the invention is not confinedthereto except as provided by the subjoined claims.

Having described the invention, what is claimed as new is: g

1. A track sander for a railway vehicle having drive wheels and a framehaving a stationary sand discharging pipe depending from said frameinfront of a drive wheel on a track rail, said sander comprising atransverse slide bar, bracket means suspending said slide bar from saidframe, roller means on said slide bar rollably engaged with a portion ofeach of the drive Wheels whereby the slide bar is moved longitudinallyof its length in conformity with the lateral deflection of said drivewheels with respect to said rail in the travel of the vehicle, anauxiliary sand discharge pipe having its lower end disposed to dischargesand upon the rail in front of one of said drive wheels, 2. flexiblecoupling connecting said auxiliary pipe with the lower end of saidpermanent pipe, and an operating connection between said auxiliary pipeand said slide bar. 7

2. A track sander for a railway vehicle having drive wheels and a framehaving a stationary sand discharging pipe depending from said frame infront of a drive wheel on a track rail, said sander comprising atransverse slide bar, bracket means suspending said slide bar from saidframe, roller means on said slide bar rollably engaged with a portion ofeach of the drivewheels whereby the slide bar is moved longitudinally ofits length in conformity with the lateral deflection of said drivewheels with respect to said rail in the travel of the vehicle, anauxiliary sand discharge pipe having its lower end disposed to dischargesand upon the rail in front of one of said drive wheels, a flexiblecoupling connecting said auxiliary pipe with the lower end of saidpermanent pipe, and an operating connection between said auxiliary pipeand said slide bar, said slide bar incorporating means to adjust itslength and said bracket means permitting relative limited up and downmotion of said slide bar.

3. A track sander for a railway vehicle having drive wheels and a framehaving a stationary sand discharging pipe depending from said frame infront of a drive wheel on a track rail, said sander comprising atransverse slide bar, bracket means suspending said slide bar from saidframe, roller means on said slide bar rollably engaged with a portion ofeach of the drive wheels whereby the slide bar is moved longitudinallyof its length in conformity with the lateral deflection of said drivewheels with respect to said rail in the travel of the vehicle, anauxiliary sand discharge pipe having its lower end disposed to dischargesand upon the rail in front of one of said drive wheels, a flexiblecoupling connecting said auxiliary pipe with the lower end of saidpermanent pipe, and an operating connection between said auxiliary pipeand said slide bar, said operating connection comprising an armprojecting rigidly from said slide bar and having pivotal connectionwith said auxiliary pipe.
